What is V2X Communication?



Vehicle to Everything (V2X), referring to Vehicle to Vehicle (V2V), Vehicle to Infrastructure (V2I), Vehicle to Pedestrian (V2P) and Vehicle to Network (V2N), is a wireless technology that allows vehicles to communicate with other vehicles and its surroundings.



V2V communication is a kind of traffic control management that enables wireless data exchange among vehicles via on-board unit (OBU). Vehicles with V2V communication can broadcast real-time messages to surrounding vehicles and receive broadcast messages to provide decision-making aid for drivers. For example, vehicles with V2V communication can determine potential crash threats by analyzing data, such as location, speed, acceleration and other status elements, of other vehicles in proximity to warn drivers in time.



V2I communication is the wireless exchange of data between vehicles and road infrastructure (such as traffic light, traffic camera and roadside unit). Road infrastructure can obtain data from vehicles in proximity and broadcast real-time messages to assist traffic management. For instance, when traffic light is invisible in a foggy day, the real-time traffic light status will be displayed on the OBU's screen directly through the V2I communication to assist crossroad passing.



V2P communication involves direct communications between vehicles and pedestrians (or vulnerable road users such as cyclists) within close proximity. It is conducted through the use of wearable devices and mobile phones. With V2P communication, drivers can receive blind spot warning to avoid pedestrian collision.



V2N communication connects on-board unit to cloud platform via access network or core network to enable data exchange, storage and processing. V2N communication is mainly used for vehicle navigation, vehicle remote control, emergency rescue and car infotainment service.



V2X connects people, vehicles, infrastructure, cloud, and other transportation elements to form an organic unity, allowing vehicles to obtain more information and promoting innovation and applications in autonomous driving. With V2X communication, an intelligent transportation system can be built to enable new business model development, resources conservation, pollution reduction, traffic efficiency and safety improvement.



Established in 2004, Shenzhen Genvict Technologies Co., Ltd. （Genvict） is a publicly-listed (Stock Code: 002869) high-tech company in intelligent transportation. We are the leading intelligent equipment provider and we can offer customers the best intelligent transportation solutions.

What is ETC Transponder?

图片
ETC (Electronic Toll Collection) transponder is a small wireless communication device installed in a vehicle for electronic tolling purpose. When the vehicle passes the toll point, roadside transceiver reads out data stored in the transponder, and then the system automatically deducts the toll payable.   At present, the electronic tolling technologies vary from country to country. What are the pros and cons of ETC transponders that adopt different technologies?   1. Dedicated Short Range Communications (DSRC): It is the mainstream technology for electronic toll collection, applied in countries such as China, Japan, Korean, Singapore and most European countries. DSRC technology has higher vehicle identification precision and is mature in tolling application, but it costs relatively high in terms of in-vehicle transponder (DSRC on-board unit/OBU).   2. Radio Frequency Identification (RFID): The world's first large-scale RFID-based tolling system opened in Taiwan in 2012. Th...

ITS Applications of UHF RFID Technology

图片
  Ultra-high Radio Frequency Identification (UHF RFID), with frequency band between 860MHz and 960MHz, is contactless and automatic identification technology that identifies and programs target (generally RFID tag attached on the object) without any human intervention. Its typical communication range is 4 to 6 meters, with maximum range over 10 meters. From technical and applicable perspectives, RFID tag is not a perfect carrier for storing large amount of data, but an effective means to identify targeted object in a contactless way.   Ultra-high Radio Frequency Identification is a practical and flexible technology that can work in harsh environment and is especially suitable for automatic control application. Currently, UHF RFID technology is widely used in fields like communication transmission, industrial automation, commercial automation and identity authentication, while long-range RF products are typically applied to intelligent transportation (ITS).   1. Electronic...

What is Electronic Toll Collection?

图片
  ETC electronic toll collection  is an automatic toll system  applied to expressways, toll bridges and tunnels. Generally, the system collects the toll via wireless communication between in-vehicle transponders and roadside transceivers, and conducts settlement processing with banks via computer network. Vehicles therefore can pass through the tolling points directly without stopping to pay the toll.   Typical method for implementing electronic toll collection is tolling via wireless communication, while automatic number plate recognition (ANPR) is now starting to gain ground in some countries.   Tolling via wireless communication:   The system collects the toll via wireless communication between the roadside transceiver and in-vehicle transponder, which is the mainstream approach adopted in most of the countries. There are various types of wireless communication for tolling, ranging from dedicated short-range communication (DSRC), radio frequency identifi...
